FIRE EXTINGUISHER Filed July 8, 1929 INVENTOR 1 17/6602; 23 5/077q/7 F Patented July 14, 1931 PATENT orrrca wILHEImr B. BRoNA-NDER, or MONTCLAIR, NEW JERSEY FIRE' ExrINGUIsHER Application fil ed July 8; 19293 seriarno; 376,747.-

This-inventionrelates to .fire extinguishers. The-invention relates more particularly to fire-extinguishers of the type: utilizing: a fire extinguishing liquid, such as carbon tetrachloride. 1

The invention has: for its salient object to providea casing structure for housing a frangible'c'ontainer so constructed and arranged that thecontainer housed thereinwill be'protecte'd against'accidental breakage butcan be readily broken-When desired.

Another object of the invention is to provide an extinguisher'so constructed and arranged that" a plurality. of separately operatable containerscan' behoused therein.

Another object of the invention is to provide an extinguisher comprising acasingand containers mounted therein that is simple and practical in construction; comprises a minimum number of parts,- and can be efliciently operate'd.

pear from. the following specification taken in connection with the'drawings, which form 'a part of this application, andin which 7 Fig. 1 is: a longitudinal sectional elevation of a device constructed in accordance With the invention; Fig. 2 is R an end-'view'of one end of the constmction shown in Fig. 1'; j

Fig3-is an elevational View, broken away, showing: the central portion of the device and'clampingbracket; and

Figi is aplan view of the bracket. Theinv'ention briefly described'consists of a casinghav-inga' plurality of compartments and independently operatable frangible containers disposed in the compartments. .The containers are so supported 'that they Will'be held against accidental breakage but can be readily and quickly broken when desired to release the-'fireextinguishingi fluid or liquid containedtherein. Further details of the invention' will appear from: the following; de scription;

In-the form ofi'the inventionillustrated in Fig: 1', there is: shown a casing; consistingof twosections' A-a'nd Bl Eachsection istubular and has an open end 11 and a closedend end 12has' secured thereinlat'the central portion thereof a metallic slug oranvil 14. If desiredthe anvil r slug 14' mayhave a barb or pointed projection 15 extendingtherefrcni.

The open end ll of each section is threaded as shownat 16and-t-he two ends 11* are threaded into a coupling having a disk or Wall 17 and internally threaded sleeves '18 and 19.

Each section houses a: frangible container QOWhlCh' seats at one end against a pad 21 disposed against the coupling Wall 17. At the other eindieach container has a nipple 22 engaged by a spring 23'WhlCh' seats against the closed end of the section.

The containers are slidably mounted in the sections A and B and'are held against accidental endWise-movement thereinby the springs 22. 4

Suitable fire extinguishingfluid or liquid such as carbon tetrachlorideis sealed in each L container 20. v Further objects of the invention Wilh ap- The 1 tubular sections and coupling; may be supported inaclamp orbracket of any suitable construction. One forni' of bracket is Sll0WI1lIlF1g'.4: and'comprises a base 25 and tvvo'sets-of-resilient clampingarms 26 and-27 adapted to embrace the sectionsA and B outside the sleeves18 and=19 of th'e' coupling.

In case of fire the device is grasped and pulledaway from. the bracket and givenxa suddenlongitudinalthrust in one direction.

This Will cause one of the containers to slide longitudinallyand the nippl'e'22- of the container will strike the anvil-or slugl i and be broken.

The fire extinguishing liqu-id will then escape from the container and can-be sprinkled on the' fire through'the perforations 13. If it, is found-that the contents of one containeris not suflicient' to'extinguish the fire, the other container can be broken in a similar manner andthe Contents, can be utilized I e If desired,-the nipple vportion 221 ofthe container may be made slightly thinner than the remaining portion thereof't'o facilitate its 5 breakage and the closed-end'12 can be made thinner at the central portion thereof to permiathis' porti onto-be pressed inor dentedin to.- engage the nipple. 12; perforated as show'n at 13; Each closed Although one specific Y embodiment of the invention has been particularly shown and described, it will be understood that the invention is capable of modification and that changes in the construction and in the arrangement of the various cooperating parts may be made without departing from the spirit or scope of the invention, as expressed in the following claims.

What I claim is:

1. A fire extinguisher comprising a casing, a frangible container movably mounted therein, said container having fire extinguishingliquid therein, a spring for holding the container against movement, and means engageable by the container for breaking the container when the container 1s moved in the casing against the force of the spring, the weight of the container and liquid therein being sufficient to overcome the action of the spring when the bodily movement of the casing and contents is interrupted.

2. A fire extinguisher comprising a casing, a frangible container slidably mounted therein, said container having fire extinguishing liquid therein, a spring for holding the container against movement, and means engageable by the container for breaking the container when the container is moved in the casing against the force of the spring, the

weight of the container and liquid therein being sufficient to overcome the action of the spring when the bodily movement of the casing and contents is interrupted.

3. A fire extinguisher comprising a casing having a closed end, a frangible container movably mounted in the casing, said container having fire extinguishing liquid therein, a spring bearing against the closed end and the container, and means carried by the casing for breaking the container upon movement thereof against the force of the spring, the weight of the container and liquid therein being sufficient to overcome the action of the spring when the bodily movement of the casing and contents is interrupted.

4. A fire extinguisher comprising a casing having a closed end, a frangible container movably mounted in the casing, a spring bearing against said end and thecontainer, and means carried by the casing for breaking the container upon movement thereof against the force of the spring, said casing having perforations therein to permit the escape therefrom of the contents of the container when the container is broken, the weight of the container and liquid therein being sufficient to overcome the action of the spring when the bodily movement of the casing and contents is interrupted.
